[Features]・The JOHS type is a further improvement on the GPF type, and is a high pressure series graded up to an operating pressure of 500kgf/cm^2.・This is a highly dependable plug optimized for applications such as oil pressure equipment that demand high pressure in a compact design.

[Features]・The GD-type plug is a general dry seal type plug with a standard radius position based on American standard dry seal pipe screws (NPTF) specified in ANSIB2.2.・Because the Gosho GS type plug uses this NPTF, excellent strength and tightness can be achieved without using sealing material as a dry seal type plug with hexagonal hole that has a full fitting length.

The position of the reference diameter is closer to the top face of the plug compared to the JIS R screw, and becomes flush with the screw member upon tightening. For general hydraulic pressure equipment. Hardness: 32–42 HRC.

[Features]・The GJ plug is a floating type (JIS type) plug compliant with JISB0203 standards. The standard diameter of the tapered thread is designed with a length (L) that is close the to the center so that the large tip surface is higher than the mounting surface when fitted with a PT or PS female thread.・The PT plug with square head is compliant with JIS standards as a replacement to the conventional GJ series with hexagonal head. However, the GJ plug with hexagonal head is often used for its reliable tightening characteristics to improve safety and work efficiency.

[Features]・The GM plug is a level seal type (flush type) developed by Gosho, and when the plug is inserted into a PT female screw regulated by JISB0203 (pipe taper female screws), regulation diameter products are mounted close to the large face so that the large face and mounting face are almost a single face.・Recently, it has become a major plug that is essential for hydraulic and pneumatic equipment.・Due to the GM plug advantages and its being a level seal type, it becomes flush with the main unit to which it is embedded or mounted, enabling a smarter appearance and more compact design.・A fastener is included that, when tightened, can withstand major internal pressure.・The plug is cold elastomer processed for high accuracy, and heat processed for use under high pressures.
